Description

Technical Field

[0001] The invention belongs to the field of die-casting equipment, and in particular relates to a die-casting mold with an oblique core-pulling and wedge-tightening structure. Background Art

[0002] In the automotive, aerospace and other industrial fields, the application of die-casting technology is very common, and it is widely used in the manufacturing process of various parts.

[0003] For die-casting molding technology, die-casting molds are an indispensable part. In the design process of die-casting molds, the design of the core pulling mechanism is often indispensable. The quality of its design usually directly affects whether the die-casting product can be accurately formed and demolded.

[0004] In the automotive industry, due to the large number of parts that need to be die-cast, the required die-casting molds are also different. For some special parts, it is necessary to set an oblique core pulling mechanism in the fixed mold of its die-casting mold. In the conventional design process, the oblique core pulling mechanism (including core pulling and drive mechanism) is usually set directly inside the fixed mold, which results in the fixed mold thickness of the die-casting mold being often large, which will not only increase the manufacturing cost and use cost of the die-casting mold, but also greatly increase the space occupied when the die-casting mold is set. Moreover, for scenes with limited working space, due to the increase in the thickness of the fixed mold, it is also possible that the die-casting mold cannot be set and used due to insufficient travel space of the movable mold, which brings great limitations and shortcomings.

[0005] In addition, for the existing inclined core pulling mechanism, the core pulling mechanism often does not have the function of locking in place after it is set in place. After the subsequent die-casting metal liquid is poured into the mold, the core pulling mechanism is very likely to retreat due to the hydraulic action of the metal liquid, resulting in a decrease in the molding quality of the die-casting part. Summary of the invention

[0006] In response to one or more of the above defects or improvement needs in the prior art, the present invention provides a die-casting mold with an oblique core-pulling wedge-locking structure, which can effectively meet the oblique core-pulling requirements of the die-casting mold, and effectively avoid the core pulling back during the die-casting process of the mold, reduce the fixed mold thickness of the mold, and reduce the manufacturing and use costs of the die-casting mold.

[0008] As a further improvement of the present invention, an end support block is also provided on the housing of the fixed mold; The end of the wedging section is provided with a sliding surface, and the sliding surface of the wedging section is placed on the end surface of the end support block, so that when the special-shaped wedging rod moves, the wedging section and the end support block are always in surface contact.

[0009] As a further improvement of the present invention, a stroke assembly is provided corresponding to the core-pulling drive mechanism, and the stroke assembly includes a stroke bracket, a stroke rod and a stroke plate; The stroke bracket is fixedly connected to the sliding seat, one end of the stroke rod is connected to the stroke bracket, and the other end is aligned with the stroke plate; the stroke plate is fixedly arranged relative to the fixed mold, and a stroke scale or stroke indicator is arranged on the stroke plate, and the movement stroke of the core pulling drive mechanism is judged by the translational movement of the stroke rod relative to the stroke plate.

[0010] As a further improvement of the present invention, a core inserting limit block is provided on the housing of the fixed mold corresponding to the sliding seat; The core inserting limit block is arranged between the sliding seat and the core pulling connecting rod, and is used to limit the displacement of the sliding seat during the inclined core pulling setting process.

[0011] As a further improvement of the present invention, a core pulling limit block is provided on the side of the slider away from the core pulling connecting rod, for limiting the displacement of the slider when the oblique core pulling is performed.

[0012] As a further improvement of the present invention, corresponding to the sliding assembly between the slider and the fixed mold, a slide rail is provided on the shell of the fixed mold, and the top of the slider is slidably assembled in the slide rail.

[0027] Example: See also Figure 1~Figure 3 The die-casting mold with an oblique core-pulling wedge-tightening structure in the preferred embodiment of the present invention includes a fixed mold 100 and a movable mold 200, and a mold core is arranged on the side opposite to each other, so that the fixed mold 100 and the movable mold 200 form a corresponding cavity for die-casting of parts after the fixed mold 100 and the movable mold 200 are molded together.

[0028] like Figure 1 As shown in , it can be seen that for the die-casting mold in the preferred embodiment, when it is actually set, the core pulling mechanism can be set on both the fixed mold 100 and the movable mold 200, and the preferred embodiment focuses on the core pulling mechanism set on the fixed mold 100. As for how to set the core pulling mechanism on the movable mold 200, it is not the focus of the preferred embodiment, and it can be quickly realized by using mature technology in the prior art, so it will not be elaborated here.

[0029] Specifically, for the die-casting mold in the preferred embodiment, the core pulling mechanism arranged on the fixed mold 100 is an inclined core pulling structure, and based on its setting, an inclined core pulling wedge structure is formed on the die-casting mold, which can effectively prevent the core pulling from retreating during the use of the die-casting mold while meeting the core pulling requirements of the fixed mold 100.

[0030] It should be noted that when the fixed mold 100 is actually set, it is necessary to set components such as inserts and cores inside the mold shell. This is not the focus of the preferred embodiment of the present invention, so it will not be described in detail in the subsequent records.

[0031] like Figure 3 As shown in the figure, the core pulling mechanism on the fixed mold 100 in the preferred embodiment includes an oblique core pulling 1, a core pulling transmission assembly and a core pulling drive mechanism 7. Among them, the oblique core pulling 1 is a rod-shaped structure, and its axis forms an acute angle with the axis of the fixed mold 100 at a certain angle. It is assembled with the core pulling transmission assembly through the core pulling connecting rod 2, and then the core pulling process of the oblique core pulling 1 is completed through the drive of the core pulling transmission assembly.

[0032] In more detail, the end of the inclined core puller 1 in the preferred embodiment is sleeved with the end of the core puller connecting rod 2, and a through hole is obliquely opened on the core puller connecting rod 2 to facilitate assembly with the core puller transmission assembly. In actual setting, the axis of the oblique through hole is intersected with the axis of the core puller connecting rod 2.

[0033] Meanwhile, the core pulling transmission assembly in the preferred embodiment includes a special-shaped wedging rod 3 and a corresponding sliding seat 5. The special-shaped wedging rod 3 is a special-shaped rod structure, which includes a wedging section 301 and a transmission section 302, and the axes of the two sections of the rod body intersect and form a certain obtuse angle with each other.

[0034] More specifically, the slider seat 5 in the preferred embodiment is formed with a slider through hole for assembling the transmission section 302, one end of the slider through hole faces the side wall of the fixed mold 100, and the other end faces the core-pulling connecting rod 2. At the same time, the slider seat 5 is slidably assembled on the housing of the fixed mold 100 through a plurality of mounting connectors, so that the slider seat 5 can reciprocate in the axial direction of the slider through hole.

[0035] During actual assembly, the transmission section 302 passes through the slide hole, and is fixedly connected to the slide seat 5 through a plurality of connecting pieces after being passed through the slide hole, so that the slide seat 5 and the transmission section 302 can slide synchronously.

[0036] In a specific preferred embodiment, corresponding to the fixation of the slider seat 5, a slide rail for the reciprocating sliding of the slider seat 5 is formed on the shell of the fixed mold 100, and the slide rail includes two sliders arranged in a pair, and a slide groove that can be slidably matched with the top of the slider seat 5 is formed between the two sliders. The top of the slider seat 5 slides and matches in the slide groove, and completes the sliding action process under the guidance of the slide groove.

[0037] In another preferred embodiment, it is further preferred to respectively set pressure strips on both lateral sides of the slider seat 5, and the two pressure strips are respectively connected to the outer wall surface of the shell of the fixed mold 100; more preferably, a pressure plate is further set on the side of the two pressure strips away from the fixed mold 100, so that the slider seat 5 can be set in the movement cavity surrounded by the two pressure strips, the pressure plate, and the outer wall surface of the fixed mold 100, thereby ensuring the reliability of the movement of the slider seat 5. It can be understood that in this embodiment, the slider seat 5 does not need to be directly slidably connected to the fixed mold 100, and it can complete the sliding translation relative to the fixed mold 100 in the movement cavity surrounded by the two pressure strips and the pressure plate.

[0038] After the assembly is completed, the wedging section 301 coaxially passes through the through hole on the core pulling connecting rod 2 and matches the sliding clearance therewith, so that the wedging section 301 and the core pulling connecting rod 2 can slide relative to each other, and the driving force borne by the wedging section 301 is used to provide an axial motion vector for the core pulling connecting rod 2, thereby completing the core pulling process of the oblique core pulling 1. By assembling the special-shaped wedging rod 3 and the core pulling connecting rod 2 with each other, a wedging structure for the oblique core pulling 1 is formed in the die-casting mold.

[0039] In more detail, the end of the core pulling connecting rod 2 abuts against the end of the slider seat 5, and the two are preferably completely assembled in a surface contact manner, so as to use the slider seat 5 to provide additional support for the inclined core pulling 1. Corresponding to the surface contact assembly between the core pulling connecting rod 2 and the slider seat 5, a first sliding surface 201 is formed at the end of the core pulling connecting rod 2, and a second sliding surface 501 that fits therewith is formed at one end of the slider seat 5, and the two sliding surfaces are arranged to fit each other.

[0040] In the actual setting, the first sliding surface 201 and the second sliding surface 501 are both perpendicular to the axis of the core-pulling connecting rod 2. In this way, when the special-shaped wedging rod 3 is driven, its driving force can be decomposed into two components of force perpendicular to the axial direction of the core-pulling connecting rod 2 and parallel to the axial direction of the core-pulling connecting rod 2. The former is used to realize the relative sliding displacement between the core-pulling connecting rod 2 and the sliding seat 5, and the latter is used to realize the axial movement process of the core-pulling connecting rod 2 (that is, to realize the core insertion and core pulling process of the inclined core pulling 1).

[0041] Furthermore, the special-shaped wedging rod 3 in the corresponding preferred embodiment is also provided with an end support block 4 , which is fixed on the shell of the fixed mold 100 and is arranged in contact with the end of the wedging section 301 .

[0042] In actual setting, the end of the wedging section 301 is preferably in surface contact with the end surface of the end support block 4, and the end surface of the end support block 4 is preferably parallel to the axis of the transmission section 302; accordingly, a sliding surface parallel to the axis of the transmission section 302 is provided at the end of the wedging section 301, that is, Figure 3 The third sliding surface 303 shown in FIG. By setting the end support block 4, the wedging section 301 of the special-shaped wedging rod 3 is always in surface contact with the end support block 4 when the special-shaped wedging rod 3 performs translational motion, and the end support block 4 reliably completes the reliable support of the special-shaped wedging rod 3 and accurately guides the translational motion of the special-shaped wedging rod 3.

[0043] More specifically, the core pulling drive mechanism 7 in the preferred embodiment is preferably a core pulling cylinder, the axis of its output shaft is parallel to or coincides with the axis of the transmission section 302, and the end of the output shaft is connected to the end of the transmission section 302 through a core pulling connector 701.

[0044] It can be seen that the core-pulling drive mechanism 7 in the preferred embodiment is arranged on one side of the housing of the fixed mold 100, and the axis of its output shaft is further preferably perpendicular to the axis of the fixed mold 100. In this way, the core-pulling drive mechanism 7 can be effectively arranged laterally on the housing of the fixed mold 100, and the core-pulling drive mechanism 7 can be arranged by utilizing the space around the housing, thereby effectively reducing the overall thickness of the fixed mold 100.

[0045] In actual setting, the core pulling drive mechanism 7 is fixed by connecting to the mounting bracket 6 on the outer peripheral side wall of the fixed mold 100. The external placement of the core pulling drive mechanism 7 realizes the core pulling requirement of the inclined core pulling mechanism while avoiding an increase in the structural thickness of the fixed mold 100.

[0046] Further preferably, in order to accurately determine the core pulling stroke of the core pulling drive mechanism 7, a stroke assembly is preferably provided, which includes a stroke bracket 702, a stroke rod 703 and a stroke plate 704. Among them, the stroke bracket 702 is fixedly connected to the slider seat 5, and the translation of the slider seat 5 can drive the stroke bracket 702 to move accordingly. Accordingly, the stroke rod 703 is arranged parallel to the output shaft of the core pulling drive mechanism 7, one end of which is fixedly connected to the stroke bracket 702, and the other end is assembled in alignment with the stroke plate 704.

[0047] The stroke plate 704 in the preferred embodiment is arranged on the top of the core pulling drive mechanism 7, which is fixed relative to the fixed mold 100, and preferably a stroke scale or stroke indicator is provided on the stroke plate 704. By utilizing the translational movement of the stroke rod 703, it is possible to achieve alignment with different stroke scales or stroke indicators on the stroke plate 704, and then accurately judge the driving stroke of the travel seat 5, thereby realizing the control and judgment of the movement stroke of the inclined core pulling 1.

[0048] More preferably, in order to ensure the reliability of the motion control of the inclined core-pulling mechanism, a corresponding limiting mechanism is preferably provided on the outer wall surface of the fixed mold 100. Figure 3 In the preferred embodiment, a core insertion limit block 502 is provided on the outer wall surface of the fixed mold 100 corresponding to the movement of the sliding seat 5, which is arranged between the sliding seat 5 and the core pulling connecting rod 2, and is used to limit the core insertion position of the inclined core pulling 1 to avoid excessive translation of the sliding seat 5 during the core insertion movement, thereby ensuring the normal operation of the inclined core pulling mechanism.

[0049] It is understandable that, according to actual setting needs, a core pulling limit block can be preferably provided on the side of the sliding seat 5 away from the core pulling connecting rod 2 to limit the core pulling stroke of the inclined core pulling mechanism to ensure the accuracy and reliability of the core pulling process.

[0050] The die-casting mold with an oblique core-pulling and wedge-locking structure in the present invention has a compact structure and is easy to use. It can effectively meet the oblique core-pulling requirements of the fixed mold of the die-casting mold and avoid the core-pulling retreat during the use of the die-casting mold. While ensuring the molding quality of the die-cast parts, the thickness of the fixed mold is greatly reduced, the convenience of using the die-casting mold in the case of limited travel space in the factory is improved, the use cost of the die-casting mold is reduced, and it has good practical value.

[0051] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
